Oahu residents have until Monday to voice their concerns about a proposed zipline going up above Royal Summit.

The Department of Land and Natural Resources held a public hearing Wednesday at Waimalu Elementary to listen to residents’ concerns, and to go over the zipline’s environmental impact statement.

“People don’t get on ziplines and keep their mouth shut. They are going to be squealing and screaming. Noise carries. It is going to come on down to the residents,” said an area resident.

“We want to be good neighbors and we want to work with the community and be responsible neighbors. We are concerned with your safety and your security,” Towne Development President Christopher Lau said.

Towne Development owns 447 acres above Royal Summit, and wants to build a zipline on its land.

The DLNR land board will gather all the public testimony, and will decide whether or not to approve the project.
